FIELD OF THE INVENTION

The present invention relates to a new hybrid tomato (Solanum lycopersicum) variety designated 72-018 RZ.

BACKGROUND OF THE INVENTION

Tomato plants of the species Solanum lycopersicum belong to the nightshade family, also known as Solanaceae. Within this family it is nowadays grouped in the genus Solanum, which does not only harbor tomato, but also the important food crops potato and eggplant. It is a perennial, herbaceous, flowering plant species which is native to South America.

Other species that are related to tomato within the Solanum genus are Solanum pimpinellifolium, Solanum chilense, Solanum peruvianum and Solanum habrochaites. Although it is known that crossing can be considerably difficult, these species are used to obtain traits that are valuable in growing tomato. In the recent history, advancement in tomato breeding has led to tomato varieties having, for example higher yield, higher disease resistance and increased shelf life.

Tomato plants are being cultivated worldwide for their highly nutritious fruits. The tomato fruit is consumed in various ways, including raw, as an ingredient in many dishes and sauces, and in drinks. While it is botanically a fruit, it is considered a vegetable for culinary purposes. The fruit is rich in lycopene, which may have beneficial health effects. In 2009, the total acreage for both fresh and processing tomatoes in the United States was approximately 442,100 acres, with a total production of about 14,141,920 tons (source: USDA).

Commercial vegetable production, including the production of tomato, is affected by many conditions. The choice of the grower for a certain variety is a determining factor, and forms the genetic basis for the result that can be attained. In addition, there are many external factors that influence the outcome. Growing conditions like climate, soil, and the use of inputs like fertilizer play a major role. There are various ways of cultivating tomatoes, among which, the most common are: open field, greenhouse and shade house production. Although the species can be grown under a wide range of climatic conditions, it performs most successfully under dry and warm conditions. In addition to this, the presence of pests and diseases also affects the total yield that can be reached.

In order to create tomato varieties that are satisfying the needs of growers and/or consumers, many considerations have to be taken into account. The goal is to combine within a single variety or hybrid an improved combination of desirable traits from the parental germplasms. These traits may include higher yield, field performance, fruit and agronomic quality such as firmness, color, content in soluble solids, acidity and viscosity, resistance to diseases and insects, and tolerance to drought and heat. With mechanical harvesting of the tomato fruits for processing purpose, i.e., juice, paste, catsup, etc., uniformity of plant characteristics such as germination, growth rate, maturity, and plant uniformity is also important.

Tomato is a simple diploid species with twelve pairs of chromosomes. The cultivated tomato is self-fertile and almost exclusively self-pollinating. The tomato flowers are hermaphrodites. Tomato cultivars were initially open-pollinated, such as many well-known heirloom tomatoes, but also varieties were developed for large scale growing facilities. Nowadays, especially in a professional growing setting these cultivars are replaced by better yielding hybrids. Due to its wide dissemination and high value, tomato has been intensively bred. This explains why such a wide array of tomatoes are now available. The size may range from small to large, and there are cherry, plum, pear, standard, and beefsteak types. Tomatoes may be grouped by the amount of time it takes for the plants to mature fruit for harvest; in general the cultivars are considered to be early, midseason or late-maturing. Tomatoes can also be grouped by the plant's growing habit, being determinate or indeterminate. Determinate plants tend to grow their foliage first, then set flowers that mature into fruit if pollination is successful. All of the fruit tend to ripen on a plant at about the same time. Indeterminate tomatoes start out by growing some foliage, then continue to produce foliage and flowers throughout the growing season. These plants will tend to have tomato fruit in different stages of maturity at any given time. More recent developments in tomato breeding have led to a wider array of fruit color. In addition to the standard red ripe color, tomatoes can be creamy white, lime green, pink, yellow, golden, or orange.

Also breeding for multiple disease and pest resistances is an important aspect in providing varieties for multiple growing systems and climates. These diseases can be the result of attacks of either nematodes, bacteria, fungi, viruses and/or insects. Important micro-organisms causing such diseases in tomato plants and their fruits in this respect include: Meloidogyne incognita (Mi), Verticillium dahliae race 0 (Vd), Fusarium oxysporum f. sp. lycopersici race 0 (ex1) and race 1 (ex2) (Fo1), Fusarium oxysporum f. sp. radicis lycopersici (For), Cladosporium fulvum groups A, B, C, D and E (Ff), Tomato Mosaic Virus (ToMV) strain 0, 1 and 2, Stemphylium spp., Tomato Spotted Wilt Virus (TSWV) and Oidium neolycopersici (On).

The way in which fruits from tomato plants are harvested is also relevant. When the fruits are not ripe at the same time, single harvest of fruits has to be applied in order to provide a fresh product to the consumer. In the case that fruits of one truss are ripening synchronous, the whole truss can be harvested and be marketed. To support this development, the interest for breeding of uniform ripening trusses has increased in the recent years.

Oidium neolycopersici is the causal agent of powdery mildew disease in tomato. The lack of a sexual stage hampers the exact identification of this pathogen, but it is believed to belong to the Ascomycetes. The fungus causes powdery white lesions on the adaxial tomato leaf surface and might also infect other abaxial surfaces, the petioles and the calyx. The tomato fruit generally remains uninfected. Severe infection of a tomato plant might result in premature senescence, leaf chlorosis and a marked reduction of the tomato fruit size. (Jones et al. Mol. Plant Pathol. 2(6), 303-309, 2001)

Silvering in tomato, also known as ‘chimera’ is a disorder that is not related to a disease caused by bacteria, viruses, insects or a combination thereof. It is called ‘head silvering’ when it affects the leaves that are formed in the shoot apical meristem of tomato plants. This disorder primarily affects tomato that is grown in protected conditions, especially in northern latitude areas of production. The white or silver color in the tissues of the leaves is caused by large intracellular spaces which develop through an abnormal formation of palisade tissue of the leaf. This happens at a very early stage of development. The main factor to positively and negatively influence this phenomenon is a drastic decrease of temperature, especially at the level of the shoot apical meristem. Silvering thus affects general plant condition but might also result in deformed fruits, optionally showing greenish to yellow streaks (Blancard et al. in Tomato Diseases: Identification, Biology and Control, Manson Publishing, 2012).

DETAILED DESCRIPTION OF THE INVENTION

The invention provides methods and compositions relating to plants, seeds and derivatives of a new hybrid tomato variety herein referred to as hybrid tomato variety 72-018 RZ. 72-018 RZ is a hybrid plant variety that is uniform and distinct from other such hybrids, and may be stably produced after a cycle of reproduction.

There are numerous steps in the development of any novel plant with desirable characteristics. Selection of traits is a very important aspect of plant breeding. Once desirable traits are identified, the plants with those desirable traits are crossed in order to recombine the desirable traits and through selection, varieties or parent lines are developed. The goal is to combine in a single variety or hybrid an improved combination of desirable traits from the parent plant or plants. These important traits may include but are not limited to higher yield, field performance, fruit and agronomic quality such as fruit shape, color and length, resistance to diseases and insects, and tolerance to drought and heat.

Choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of cultivar used commercially (e.g., F1 hybrid cultivar, pureline cultivar, etc.). Popular selection methods commonly include but are not limited to pedigree selection, modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method. Backcross breeding is used to transfer one or a few favorable genes coding for a highly heritable trait into a desirable cultivar. This approach is used extensively for breeding disease-resistant cultivars. Various recurrent selection techniques are used to improve quantitatively inherited traits controlled by numerous genes. The use of recurrent selection in self-pollinating crops depends on the ease of pollination, the frequency of successful hybrids from each pollination, and the number of hybrid offspring from each successful cross.

The development of commercial tomato hybrids relates to the development of tomato parental lines, the crossing of these lines, and the evaluation of the crosses. Pedigree breeding and recurrent selection breeding methods are used to develop cultivars from breeding populations. Breeding programs combine desirable traits from two or more varieties or various broad-based sources into breeding pools from which lines are developed by selfing and selection of desired phenotypes. The new lines are crossed with other lines and the hybrids from these crosses are evaluated to determine which have the desirable characteristics.

Pedigree breeding is used commonly for the improvement and development of inbred lines of self-pollinating or cross-pollinating crops. Two parents which possess favorable, complementary traits are crossed to produce an F1. An F2 population is produced by selfing one or several F1s or by intercrossing two F1s (sib mating). Selection of the best individuals is usually begun in the F2 population; then, beginning in the F3, generally the best individuals in the best families are selected. Replicated testing of families, or hybrid combinations involving individuals of these families, often follows in the F4 generation to improve the effectiveness of selection for traits with low heritability. At an advanced stage of inbreeding suitable lines are used as parents to produce F1 hybrids, which are subsequently tested for potential release as new varieties or cultivars.

Mass and recurrent selections may be used to improve populations of either self- or cross-pollinating crops. A genetically variable population of heterozygous individuals is either identified or created by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simply inherited, highly heritable trait into a desirable homozygous cultivar or line that is the recurrent parent. The source of the trait to be transferred is called the donor parent. The resulting plant is expected to have the attributes of the recurrent parent (e.g. the cultivar or parent line) and the desirable trait transferred from the donor parent. After the initial cross, individuals possessing the phenotype of the donor parent for the preferred trait are selected and repeatedly crossed (backcrossed) to the recurrent parent. The resulting plant is expected to have the attributes of the recurrent parent (e.g. the cultivar or parent line) and the desirable trait transferred from the donor parent.

Other methods of breeding may also relate to the single-seed descent procedure which refers to planting a segregating population, harvesting a sample of one seed per plant, and using the one-seed sample to plant the next generation. When the population has been advanced from the F2 to the desired level of inbreeding, the plants from which lines are derived will each trace to different F2 individuals. The number of plants in a population declines each generation due to failure of some seeds to germinate or some plants to produce at least one seed. As a result, not all of the F2 plants originally sampled in the population will be represented by a progeny when generation advance is completed.

In addition to phenotypic observations, the genotype of a plant may also be examined. There are many laboratory-based techniques available for the analysis, comparison and characterization of plant genotype; these techniques include but are not limited to Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length polymorphisms (AFLPs), Simple Sequence Repeats (SSRs—which are also referred to as Microsatellites), and Single Nucleotide Polymorphisms (SNPs). Nowadays, sequence-based methods are utilizing SNPs that are randomly distributed across genomes as a common tool for genotyping (e.g. Elshire et al. PloS One Vol. 6: e19379, 2011; Poland et al. PloS One Vol. 7: e32253; Truong et al. PloS One Vol. 7 number 5: e37565, 2012).

With any of the aforementioned genotyping techniques, polymorphisms may be detected when the genotype and/or sequence of the plant of interest is compared to the genotype and/or sequence of one or more reference plants. As used herein, the genotype and/or sequence of a reference plant may be derived from, but is not limited to, any one of the following: parental lines, closely related plant varieties or species, complete genome sequence of a related plant variety or species, or the de novo assembled genome sequence of one or more related plant varieties or species.

Molecular markers, which include markers identified through the use of techniques such as Isozyme Electrophoresis, RFLPs, RAPDs, AP-PCR, DAF, SCARs, AFLPs, SSRs, and SNPs, may be used in plant breeding. One use of molecular markers is Quantitative Trait Loci (QTL) mapping. QTL mapping is the use of markers which are known to be closely linked to alleles that have measurable effects on a quantitative trait. Selection in the breeding process is based upon the accumulation of markers linked to the positive effecting alleles and/or the elimination of the markers linked to the negative effecting alleles from the plant's genome.

Molecular markers may also be used during the breeding process for the selection of qualitative traits. For example, markers closely linked to alleles or markers containing sequences within the actual alleles of interest may be used to select plants that contain the alleles of interest during a backcrossing breeding program. The markers may also be used to select toward the genome of the recurrent parent and against the markers of the donor parent. This procedure attempts to minimize the amount of genome from the donor parent that remains in the selected plants. It may also be used to reduce the number of crosses back to the recurrent parent needed in a backcrossing program. The use of molecular markers in the selection process is often called genetic marker enhanced selection or marker-assisted selection. Molecular markers may also be used to identify and exclude certain sources of germplasm as parental varieties or ancestors of a plant by providing a means of tracking genetic profiles through crosses.

Mutation breeding is another method of introducing new traits into tomato varieties. Mutations that occur spontaneously or are artificially induced may be useful sources of variability for a plant breeder. The goal of artificial mutagenesis is to increase the rate of mutation for a desired characteristic. Mutation rates may be increased by many different means including temperature, long-term seed storage, tissue culture conditions, radiation (such as X-rays, Gamma rays, neutrons, Beta radiation, or ultraviolet radiation), chemical mutagens (such as base analogs like 5-bromo-uracil), antibiotics, alkylating agents (such as sulfur mustards, nitrogen mustards, epoxides, ethyleneamines, sulfates, sulfonates, sulfones, or lactones), azide, hydroxylamine, nitrous acid or acridines. Once a desired trait is observed through mutagenesis the trait may then be incorporated into existing germplasm by traditional breeding techniques. Details of mutation breeding may be found in Principles of Cultivar Development by Fehr, Macmillan Publishing Company, 1993.

The production of doubled haploids may also be used for the development of homozygous lines in a breeding program. Doubled haploids are produced by the doubling of one set of chromosomes from a heterozygous plant to produce a completely homozygous individual. For example, see Wan et al., Theor. Appl. Genet., 77:889-892, 1989.

The tomato plant of the invention may be arrived at through crossing of inbred lines or through selection of the disclosed desirable characteristics by any of the breeding and selection methods mentioned above.

Hybrid tomato variety 72-018 RZ is made from a cross between two uniform parent lines. The female parent is line PLT2001F. This line is an F8 selection from a cross between an old F2 population having code BPT001, and a hybrid having internal code HT1101. Selection up to the F8 generation is performed in the Netherlands. The resulting F8 parent has a distinguishing greenish cream color.

The male parent of this line is PLT2002M. It is also an F8 developed through continuous inbreeding from a specialty plum variety designated HT1202. The resulting line that is used as the male parent has a remarkable soft yellowish color. In 2015 the first cross between PLT2001F and PLT2002M was made in the Netherlands, and several years of testing and observation followed. The attractive cream color and unique taste resulted in selection of the hybrid for commercialization, and it was designated code 72-018 RZ.

In one embodiment, a plant of the invention has all the morphological and physiological characteristics of tomato variety 72-018 RZ. These characteristics of a tomato plant of the invention, e.g. variety 72-018 RZ, are summarized in Table 1. In Table 2 the main differences with a comparable publicly available variety are given, when grown under the same conditions.

The information presented in Tables 1 and 2 was determined in trial experiments in accordance with official Dutch plant variety registration authorities (Naktuinbouw).

The terminology and descriptors used by the Naktuinbouw, and accordingly in Table 1, are in line with the descriptors of the “UPOV Guidelines for the Conduct of Tests for Distinctness, Uniformity, and Stability”, or the “Test Guidelines” for Solanum lycopersicum. The “Test Guidelines” indicate reference varieties for the descriptors or characteristics that are included in the list. Test guidelines for all crops may be accessed through the UPOV website, at www.upov.int/test guidelines/en/index.jsp. For tomato, the most recent English Test Guideline TG/44/11, including reference varieties, was updated in 2011 and 2013, and is accessible at www.upov.int/edocs/tgdocs/en/tg044.pdf. The terminology and descriptors used in these tables are in line with the official terminology as of the filing date, and are thus clear for a person skilled in the art.

In addition the “Calibration book of Lycopersicon esculentum Mill.—Tomato” (Version 1, NAKTuinbouw, 2010) provides even more detailed reference information on most of the characteristics that are included in Table 1.

In an embodiment, the invention relates to a tomato plant that has all the morphological and physiological characteristics of the invention and has acquired said characteristics by introduction of the genetic information that is responsible for the characteristics from a suitable source, either by conventional breeding, or genetic modification, in particular by cisgenesis or transgenesis. Cisgenesis is genetic modification of plants with a natural gene, coding for an (agricultural) trait, from the crop plant itself or from a sexually compatible donor plant. Transgenesis is genetic modification of a plant with a gene from a non-crossable species or a synthetic gene.

Just as useful traits may be introduced into a hybrid by backcrossing the trait into one or both parents, useful traits may be introduced directly into the plant of the invention, being a plant of hybrid tomato variety 72-018 RZ, by genetic transformation techniques; and, such plants of hybrid tomato variety 72-018 RZ that have additional genetic information introduced into the genome or that express additional traits by having the DNA coding therefore introduced into the genome via transformation techniques, are within the ambit of the invention, as well as uses of such plants, and the making of such plants.

Genetic transformation may therefore be used to insert a selected transgene into the plant of the invention, being a plant of hybrid tomato variety 72-018 RZ or may, alternatively, be used for the preparation of transgenes which may be introduced by backcrossing. Methods for the transformation of plants, including tomato, are well known to those of skill in the art.

Vectors used for the transformation of tomato cells are not limited so long as the vector may express an inserted DNA in the cells. For example, vectors which may comprise promoters for constitutive gene expression in tomato cells (e.g., cauliflower mosaic virus 35S promoter) and promoters inducible by exogenous stimuli may be used. Examples of suitable vectors include pBI binary vector. The “tomato cell” into which the vector is to be introduced includes various forms of tomato cells, such as cultured cell suspensions, protoplasts, leaf sections, and callus. A vector may be introduced into tomato cells by known methods, such as the polyethylene glycol method, polycation method, electroporation, Agrobacterium-mediated transfer, particle bombardment and direct DNA uptake by protoplasts. To effect transformation by electroporation, one may employ either friable tissues, such as a suspension culture of cells or embryogenic callus or alternatively one may transform immature embryos or other organized tissue directly. In this technique, one would partially degrade the cell walls of the chosen cells by exposing them to pectin-degrading enzymes (pectolyases) or mechanically wound tissues in a controlled manner.

A particularly efficient method for delivering transforming DNA segments to plant cells is microprojectile bombardment. In this method, particles are coated with nucleic acids and delivered into cells by a propelling force. Exemplary particles include those which may be comprised of tungsten, platinum, and preferably, gold. For the bombardment, cells in suspension are concentrated on filters or solid culture medium. Alternatively, immature embryos or other target cells may be arranged on solid culture medium. The cells to be bombarded are positioned at an appropriate distance below the macroprojectile stopping plate. An illustrative embodiment of a method for delivering DNA into plant cells by acceleration is the Biolistics Particle Delivery System, which may be used to propel particles coated with DNA or cells through a screen, such as a stainless steel or Nytex screen, onto a surface covered with target tomato cells. The screen disperses the particles so that they are not delivered to the recipient cells in large aggregates. It is believed that a screen intervening between the projectile apparatus and the cells to be bombarded reduces the size of projectiles aggregate and may contribute to a higher frequency of transformation by reducing the damage inflicted on the recipient cells by projectiles that are too large. Microprojectile bombardment techniques are widely applicable, and may be used to transform virtually any plant species, including a plant of tomato variety 72-018 RZ.

Agrobacterium-mediated transfer is another widely applicable system for introducing gene loci into plant cells. An advantage of the technique is that DNA may be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. Agrobacterium transformation vectors are capable of replication in E. coli as well as Agrobacterium, allowing for convenient manipulations. Moreover, advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vectors to facilitate the construction of vectors capable of expressing various polypeptide coding genes. The vectors have convenient multi-linker regions flanked by a promoter and a polyadenylation site for direct expression of inserted polypeptide coding genes. Additionally, Agrobacterium containing both armed and disarmed Ti genes may be used for transformation. In those plant strains where Agrobacterium-mediated transformation is efficient, it is the method of choice because of the facile and defined nature of the gene locus transfer. The use of Agrobacterium-mediated plant integrating vectors to introduce DNA into plant cells, including tomato plant cells, is well known in the art (See, e.g., U.S. Pat. Nos. 7,250,560 and 5,563,055).

Transformation of plant protoplasts also may be achieved using methods based on calcium phosphate precipitation, polyethylene glycol treatment, electroporation, and combinations of these treatments.

A number of promoters have utility for plant gene expression for any gene of interest including but not limited to selectable markers, scoreable markers, genes for pest tolerance, disease resistance, nutritional enhancements and any other gene of agronomic interest. Examples of constitutive promoters useful for tomato plant gene expression include, but are not limited to, the cauliflower mosaic virus (CaMV) P-35S promoter, a tandemly duplicated version of the CaMV 35S promoter, the enhanced 35S promoter (P-e35S), the nopaline synthase promoter, the octopine synthase promoter, the figwort mosaic virus (P-FMV) promoter (see U.S. Pat. No. 5,378,619), an enhanced version of the FMV promoter (P-eFMV) where the promoter sequence of P-FMV is duplicated in tandem, the cauliflower mosaic virus 19S promoter, a sugarcane bacilliform virus promoter, a commelina yellow mottle virus promoter, the promoter for the thylakoid membrane proteins from spinach (psaD, psaF, psaE, PC, FNR, atpC, atpD, cab, rbcS) (see U.S. Pat. No. 7,161,061), the CAB-1 promoter from spinach (see U.S. Pat. No. 7,663,027), the promoter from maize prolamin seed storage protein (see U.S. Pat. No. 7,119,255), and other plant DNA virus promoters known to express in plant cells. A variety of plant gene promoters that are regulated in response to environmental, hormonal, chemical, and/or developmental signals may be used for expression of an operably linked gene in plant cells, including promoters regulated by (1) heat, (2) light (e.g., pea rbcS-3A promoter, maize rbcS promoter, or chlorophyll a/b-binding protein promoter), (3) hormones, such as abscisic acid, (4) wounding (e.g., wunl, or (5) chemicals such as methyl jasmonate, salicylic acid, or Safener. It may also be advantageous to employ organ-specific promoters.

Exemplary nucleic acids which may be introduced to the tomato variety of this invention include, for example, DNA sequences or genes from another species, or even genes or sequences which originate from or are present in tomato species, but are incorporated into recipient cells by genetic engineering methods rather than classical reproduction or breeding techniques. However, the term “exogenous” is also intended to refer to genes that are not normally present in the cell being transformed, or perhaps simply not present in the form, structure, etc., as found in the transforming DNA segment or gene, or genes which are normally present and that one desires to express in a manner that differs from the natural expression pattern, e.g., to over-express. Thus, the term “exogenous” gene or DNA is intended to refer to any gene or DNA segment that is introduced into a recipient cell, regardless of whether a similar gene may already be present in such a cell. The type of DNA included in the exogenous DNA may include DNA which is already present in the plant cell, DNA from another plant, DNA from a different organism, or a DNA generated externally, such as a DNA sequence containing an antisense message of a gene, or a DNA sequence encoding a synthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and could potentially be introduced into a plant of tomato variety 72-018 RZ. Non-limiting examples of particular genes and corresponding phenotypes one may choose to introduce into a tomato plant include one or more genes for insect tolerance, pest tolerance such as genes for fungal disease control, herbicide tolerance, and genes for quality improvements such as yield, nutritional enhancements, environmental or stress tolerances, or any desirable changes in plant physiology, growth, development, morphology or plant product(s).

Alternatively, the DNA coding sequences may affect these phenotypes by encoding a non-translatable RNA molecule that causes the targeted inhibition of expression of an endogenous gene, for example via antisense- or cosuppression-mediated mechanisms. The RNA could also be a catalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desired endogenous mRNA product. Thus, any gene which produces a protein or mRNA which expresses a phenotype or morphology change of interest is useful for the practice of the present invention. (See also U.S. Pat. No. 7,576,262, “Modified gene-silencing RNA and uses thereof.”)

Also, the invention comprehends methods for producing a seed of a 72-018 RZ-derived tomato plant which may comprise (a) crossing a plant of tomato variety 72-018 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 43549, with itself or a second tomato plant, and (b) whereby seed of a 72-018 RZ-derived tomato plant form (e.g., by allowing the plant from the cross to grow to produce seed). Such a method may further comprise (c) crossing a plant grown from 72-018 RZ-derived tomato seed with itself or with a second tomato plant to yield additional 72-018 RZ-derived tomato seed, (d) growing the additional 72-018 RZ-derived tomato seed of step (c) to yield additional 72-018 RZ-derived tomato plants, and (e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to further generate 72-018 RZ-derived tomato plants, and (f) allowing seed of the further 72-018 RZ-derived tomato plant to form. The invention also encompasses a 72-018 RZ-derived tomato plant or seed produced by such method.

Backcrossing one of the parents of a hybrid may also be used to improve an inbred plant. Backcrossing transfers a specific desirable trait from one inbred or non-inbred source to an inbred that lacks that trait. This may be accomplished, for example, by first crossing a superior inbred (A) (recurrent parent) to a donor inbred (non-recurrent parent), which carries the appropriate locus or loci for the trait in question. The progeny of this cross are then mated back to the superior recurrent parent (A) followed by selection in the resultant progeny for the desired trait to be transferred from the non-recurrent parent. After five or more backcross generations with selection for the desired trait, the progeny are heterozygous for loci controlling the characteristic being transferred, but are like the superior parent for most or almost all other loci. The last backcross generation would be selfed to give pure breeding progeny for the trait being transferred.

The invention also encompasses a method of introducing a desired trait into a plant of hybrid tomato variety 72-018 RZ which may comprise: (a) crossing a parent plant of hybrid tomato variety 72-018 RZ, with a second tomato plant that may comprise the desired trait to produce F1 progeny; (b) selecting an F1 progeny that may comprise the desired trait; (c) crossing the selected F1 progeny with said parent plant of tomato variety 72-018 RZ, to produce backcross progeny and (d) selecting backcross progeny which may comprise the desired trait and the physiological and morphological characteristics of said parent plant of tomato variety 72-018 RZ, when grown in the same environmental conditions.

The aforementioned method of introducing a desired trait into a plant of hybrid tomato variety 72-018 RZ could also further comprise (e) repeating steps (c) and (d) one or more times in succession to produce selected fourth or higher backcross progeny that may comprise the desired trait and the physiological and morphological characteristics of said parent plant of tomato variety 72-018 RZ and (h) crossing the backcrossed parent plant having the added desired trait with the other parent plant to obtain a plant which may comprise the desired trait and all of the physiological and morphological characteristics of a plant of tomato variety 72-018 RZ.

The invention additionally provides a method of introducing a desired trait into a plant of hybrid tomato variety 72-018 RZ by reverse breeding (See generally allowed U.S. application Ser. No. 10/487,468, published as 2006-0179498 A1), which may comprise the following steps: (a) allowing the hybrid tomato plant to produce haploid cells, while suppressing recombination, (b) growing haploid cells into diploid plants, (c) selecting those homozygous plants which together constitute the hybrid variety of the invention as parent plants for the said hybrid, (d) crossing one of the said parent plants with a plant having the desired trait, (e) crossing the selected F1 progeny with said parent plant, to produce backcross progeny; (f) selecting backcross progeny which may comprise the desired trait and the physiological and morphological characteristic of the parent plant; and, optionally, (g) repeating steps (e) and (f) one or more times in succession to produce selected fourth or higher backcross progeny that may comprise the desired trait and all of the physiological and morphological characteristics of said parent plant, (h) crossing the backcrossed parent plant having the added desired trait with the other parent plant obtained after reverse breeding to obtain a plant which may comprise the desired trait and all of the physiological and morphological characteristics of a plant of tomato variety 72-018 RZ.

The invention further involves a method of determining the genotype of a plant of tomato variety 72-018 RZ, representative seed of which has been deposited under NCIMB Accession No. NCIMB 43549, or a first generation progeny thereof, which may comprise obtaining a sample of nucleic acids from said plant and and comparing said nucleic acids to a sample of nucleic acids obtained from a reference plant, and detecting a plurality of polymorphisms between the two nucleic acid samples. This method may additionally comprise the step of storing the results of detecting the plurality of polymorphisms on a computer readable medium, or transmitting the results of detecting the plurality of polymorphisms. The plurality of polymorphisms are indicative of and/or give rise to the expression of the morphological and physiological characteristics of tomato variety 72-018 RZ.

The polymorphisms of this invention may be provided in a variety of mediums to facilitate use, e.g. a database or computer readable medium, which may also contain descriptive annotations in a form that allows a skilled artisan to examine or query the polymorphisms and obtain useful information.
